BACKGROUND OF THE INVENTION Cyclic guanosine-3 ', 5'-
Monophosphoric acid (hereinafter abbreviated as cGMP) was introduced in 1963.
It was found in the urine of rats by DF Ashman. It is now known that cGMP is widely distributed in many animal body tissues including humans. cGMP is biosynthesized from guanosine triphosphate (GTP) by the action of guanylate cyclase.

[0003] It has been experimentally confirmed that cGMP has various physiological activities. For example, cGMP causes relaxation of the heart muscle and smooth muscle. It is also involved in the formation of neuronal synapses, triggers cell differentiation, and induces lymphocyte differentiation. cGMP is metabolized to 5'-GMP by cGMP phosphodiesterase (hereinafter abbreviated as cGMP-PDE).

[0007] It is generally believed that most diseases are caused by the interaction of multiple mechanisms. therefore,
Inhibiting only one of several mechanisms is not adequate for treating disease. It may be useful to inhibit multiple causes of the disease simultaneously with one agent. In particular, having both cGMP-PDE inhibitory activity and TXA 2 inhibitory activity is useful for the prevention and / or treatment of diseases caused by platelet aggregation (eg, angina pectoris, heart failure, etc.), pulmonary hypertension, and various renal diseases. It is.
